bilirubin

Yellow breakdown product

Bilirubin is a yellow-orange pigment produced when red blood cells break down.

The liver processes it for excretion in bile, giving feces their brown color.

Elevated bilirubin causes jaundice—yellowing of the skin and eyes.

Doctors measure bilirubin levels to assess liver function and diagnose conditions like hepatitis or gallstones: The baby's bilirubin was high, so they put her under lights.
